NOTE
Note positioning and installation of top edge channel before removing.
3.Loosen set screws in back of top edge channel.
4.Using a flathead screwdriver, push down aluminum wedge inside top edge channel, until it rests in bottom of the channel. After wedge has been released from glass, remove the old glass from the top edge channel.
5.Position the top edge channel on the new glass panel in same position as removed.
NOTE
Glass must be fully inserted into top edge channel before tightening.
6.After glass is positioned in the top edge channel, tighten each set screw until glass is held into place by the aluminum wedge. Do not overtighten.
6.With aid of assistants, lift and tentatively position new glass assembly in the hinge slots. Tighten the hinge set screws. Do not overtighten.
7.Slowly lower glass to check position. If adjustment is necessary, raise glass and have assistants hold both ends. Loosen the hinge set screws, adjust the glass assembly position and retighten set screws to secure top edge channel in hinge slot. Do not overtighten.
Lift-Glass Gas Piston Replacement
WARNING
The TL series cases rely upon gas pistons to assist lifting the glass and holding it in the raised position. The glass is heavy and difficult for one person to lift alone while replacing a gas piston. Use an assistant to prevent possible glass breakage and/or personal injury.
Since gas pistons are very powerful when in compressed state, follow these cautions during replacement:
•Do not attempt to perform any work on case while piston is in compressed state.
•Raise glass to full UP position before beginning any work involving gas pistons.
•Do not attempt to alter a gas piston in any way.
•Do not expose a gas piston to excessive heat.
•Dispose of gas piston as soon as possible after removal.
Each lift glass panel uses four gas pistons and two hinges to support it. Example: 8’case has 2 lift glass panels with 4 hinges and 8 gas pistons.
1.Have an assitant lift and hold the glass in the full UP position. Note position and relationship of all glass lift components.
